Exchange operator formalism for an infinite family of solvable and integrable quantum systems on a plane
C. Quesne ;
Date 12 Oct 2009
AbstractThe exchange operator formalism in polar coordinates, previously considered for the Calogero-Marchioro-Wolfes problem, is generalized to a recently introduced, infinite family of exactly solvable and integrable Hamiltonians $H_k$, $k=1$, 2, 3,..., on a plane. The elements of the dihedral group $D_{2k}$ are realized as operators on this plane and used to define some differential-difference operators $D_r$ and $D_{varphi}$. The latter serve to construct $D_{2k}$-extended and invariant Hamiltonians $chh_k$, from which the starting Hamiltonians $H_k$ can be retrieved by projection in the $D_{2k}$ identity representation space.
